THEORETICAL STUDY OF SPECTRAL RESPONSES OF HETEROJONCTIONS BASED ON CuInSe2 and CuInS2

Materials and Devices, 2020
In this work we study the spectral responses of thin films solar cells of heterojunctions based on CuInSe2 and CuInS2. Four-layer structures are studied according to the n+n/pp+ model. First we consider the structure  ZnO(n+)/CdS(n)/CuInS2(p)/CuInSe2(p+)

Exciton spectra of CuInSe2 crystals

Moldavian Journal of the Physical Sciences, 2005
The excitonic reflectivity spectra and the wave-length derivative reflection spectra have been investigated for CuInSe2 crystals. The n =1, n =2 and n = 3 states of A, B and C exciton series are revealed and the contours of exciton lines (n=1) are ...

Colloidal-chemistry based synthesis of quantized CuInS2/Se2 nanoparticles [PDF]

Journal of the Serbian Chemical Society, 2012
Ternary chalcogenide nanoparticles, CuInS2 and CuInSe2, were synthesized in high- temperature boiling organic non-polar solvent. The X-ray diffraction analysis revealed that both materials have tetragonal (chalcopyrite) crystal structure.
